Sarama Resources (SWA-V) May 16, '16 is pleased to announce positive results from the first phase of its 2016 aircore ("AC"), reverse-circulation ("RC") and diamond drilling campaign at the South Houndé Project (the "Project") in south-western Burkina Faso. The work forms part of an ongoing, multi-faceted exploration program which includes drilling, geological studies and geochemical and geophysical surveys.
Highlights
Infill drilling confirms wide, high-grade oxide mineralisation with an oblique strike at the MC Prospect
New high-grade, oblique mineralisation identified at the Phantom East Prospect.
Additional oblique mineralisation identified at the MC Prospect, linking known mineralised horizons and potentially giving an insight into the structural architecture of the mineralised system.
Infill and extensional drilling confirms mineral resource estimate and provides extension along strike of selected lodes at the Kenobi and MC Prospects.
Extensional drilling down-dip at the MM, Obi and Kenobi Prospects indicates lithological continuity and provides further target areas.
Highlighted downhole intersections include:
FRC984 15m @ 7.44 g/t Au from 47m - MC Prospect (infill oblique mineralisation)
FRC982 14m @ 4.12 g/t Au from 41m - MC Prospect (infill oblique mineralisation)

** denotes hole drilled at shallow angle (<~50°) to mineralisation – true width expected to be approximately 25% of downhole length
Drilling will continue to test for strike and depth extensions to thick, high-grade mineralisation at the MC Prospect.
Approximately 3,500m of diamond drilling, 1,700m of RC drilling, and 5,000m of AC drilling is planned for the Q2 2016 exploration program.
USD$3.5M (CAD$4.7M) exploration program is budgeted for 2016 including geochemical and geophysical surveys and drill programs.
Cross-Structure Drill Programs
Two small drill programs were undertaken at the MC and Phantom East Prospects to further investigate the presence of two zones of mineralisation which are part of the existing mineral resource within the Tankoro Structural Corridor (refer Figure 1). The mineralisation is interpreted to strike at approximately 070°, which is oblique to the majority of mineralisation within the corridor which strikes in a north-north-easterly ("NNE") direction. Recent geological reviews have highlighted that structural features influence the tenor and thickness of mineralisation within the system.
The programs were guided by previous drilling results, mineral resource modelling and recent gradient-array induced-polarisation ("IP") geophysical surveys which identified several anomalous areas between the predominant east-west drill lines. Drilling was designed using a range of azimuths to properly test the targets.
MC Prospect (Central Area)
A 3-hole, 300m RC drill program was undertaken in the central section of the MC Prospect. Historical drilling had intersected wide, high-grade mineralisation, leading to the interpretation of an oblique zone extending to approximately 250m vertical depth (refer Figures 1, 2 and 3). The historical drilling, while supportive of the interpretation, was sub-optimal given its east-west orientation. The recent drilling was designed on an azimuth of 330° and tested the central portion of the lode as well as the eastern extremity. Strong intersections were returned in all holes (full results are listed in Appendix A) with highlights of:
15m @ 7.44g/t Au from 47m in FRC984;
14m @ 4.12g/t Au from 41m in FRC982; and
6m @ 3.91g/t Au from 85m in FRC983.
The results confirm the existing near-surface mineral resource interpretation and highlight the potential for oblique mineralisation, possibly associated with cross-structures, to feature in the system. The wide, high-grade intersection in FRC982, located on the western edge of the mineral resource, suggesting that the mineralisation is open-ended to the west. The mineralised lode is also open to the east. Testing of these targets, as well as confirmation of the interpretation at depth, will be a high priority in upcoming drill programs.
Phantom East Prospect
A 6-hole, 320m AC drill program was undertaken in an area where mineralisation was interpreted to strike NNE (refer Figures 1 and 4). Historical drilling on a central east-west section contained numerous high-grade intersections in both oxide and fresh rock, but drilling to the north and south returned comparatively weak results, indicating the potential for mineralisation to be oblique to the east-west oriented drill fences.
Strong intersections were returned in all 6 holes of the program, confirming the tenor of the previous drilling and suggesting the presence of multiple parallel lodes, each with a true width ranging from 5-8m, striking in a north-east direction. Full results are listed in Appendix A and highlighted results include:
10m @ 7.15 g/t Au from 4m, 6m @ 3.14 g/t Au from 26m and 12m @ 2.83 g/t Au from 38m in AC2431;
8m @ 4.45 g/t Au from 20m in AC2434;
12m @ 5.78 g/t Au from 12m in AC2496; and
8m @ 2.58 g/t Au from 22m in AC2497.
Note: AC2431 was drilled at a shallow angle (<~50°) to mineralisation - true width expected to be approximately 25% of downhole length
While the area only makes a 2% contribution to the contained gold in the Project's mineral resource, the revised interpretation gives potential for the Phantom East mineralisation to be extended along strike to the east and west which will be further tested in Q2 2016. Potential for extension at depth is present, but remains a secondary focus.
MC Prospect (Northern Areas) and Kenobi Prospect
Following the successful delineation of the oblique mineralisation in the central areas of the MC and Phantom East Prospects, further preliminary testing was conducted in other parts of the mineralised system where several phases of IP surveys and historical drill intersections had indicted the potential for mineralisation with a similar orientation.
A 20-hole, 1200m AC and RC drill program in the northern area of the MC Prospect identified oblique mineralisation in two separate trends, each striking approximately 070° and measuring 300m and 150m in length (refer Figures 1 and 2). The mineralisation is interpreted to link the western and eastern mineralised horizons that are part of the existing mineral resource. The area remains lightly drill tested and the presence of the mineralisation indicates potential for repetition of mineralisation, possibly associated with cross-structures, along the main NNE mineralised horizons.
Results are listed in Appendix B. Highlights from the northern area of the MC Prospect include:
8m @ 3.31 g/t Au from 4m in AC2413;
14m @ 1.47g/t Au from 46m in AC2417; and
4m @ 3.11g/t Au from 16m in AC2418.
A 14-hole, 1200m AC and RC drill program at the Kenobi Prospect, with a similar focus on oblique mineralisation, returned several intersections of interest including (full results are listed in Appendix B) :
23m @ 1.73 g/t Au from 40m in FRC1000;
34m @ 0.97 g/t Au from 28m in FRC1001;
16m @ 1.19 g/t Au from 38m in FRC1002; and
14m @ 1.04 g/t Au from 27m in FRC1003.
Note: Holes were drilled at a shallow angle (<~50°) to mineralisation - true widths expected to range 30-50% of downhole lengths
The drill program has continued to intersect lower grade mineralisation that may be oriented oblique to the overall NNE trending mineralised trend. Further drilling is required to confirm the geometry of the mineralisation, but the abundance of intersections in oxide indicates potential to add to the oxide component of the mineral resource.
Other minor oblique-orientated targets in isolated areas within the MC Prospect were also tested in a 9-hole, 600m combined AC and RC drill program but returned no significant results (refer Appendix C).
Mineral Resource Infill and Extensional Drilling
A combined infill and extensional drill program, designed to confirm existing mineral resource interpretations and to investigate minor extensions along strike and down dip was undertaken at the MM, MC, Obi and Kenobi Prospects (refer Figure 1). The program, which was mainly focussed on the oxide horizon was comprised of 5,000m RC (51 holes), 1200m AC (23 holes) and 900m diamond (6 holes) drilling. Full results are listed in Appendix D.
Drilling at the MM and Obi Prospects was designed to test depth extensions to the mineral resource in areas where elevated grades were encountered in previous drilling. The mineral resource contains several higher-grade shoots along the strike of the system that offer targets at depth. In general, the drilling returned broad, lower-grade intersections indicating lithological continuity in fresh rock. Of note was the drilling at the MM Prospect where the drilling shows potential for a section of the main mineralised lodes in the west of the system be extended down-dip in fresh rock (to approximately 400m vertical depth) along a strike length of 800m. Further geological review on the controls of high-grade mineralisation within the system will be conducted prior to further testing in this area.
Drilling at the MC and Kenobi Prospects was generally oxide focussed and was designed to confirm the mineral resource estimate and investigate potential for minor extensions along strike and depth. The drilling within the mineral resource returned intersections that generally support the mineral resource estimate. Extensional drilling at the periphery of the mineral resource indicates potential for modest strike extensions to oxide mineralisation which will be tested in up-coming drill campaigns.
Deeper drilling on a single section at the Kenobi Prospect demonstrated the potential to extend selected mineralised lodes for a further 100m down-dip which adds further dimension to the system in this area which has relatively shallow drill coverage to date.
Highlighted results include:
8m @ 1.21 g/t Au from 23m in FRC962;
7m @ 1.24 g/t Au from 59m in FRC972;
9m @ 1.31 g/t Au from 88m in FRC1036;
8m @ 1.74 g/t Au from 39m in AC2351;
24m @ 1.21g/t Au from 20m in FRC922;
19m @ 1.51g/t Au from 16m in FRC926; and
11.4m @ 1.19 g/t Au from 162.5m in FRC1034.
Note: FRC1036 was drilled at a shallow angle (<~50°) to mineralisation - true width expected to be approximately 30% of downhole length
Sarama's President and CEO, Andrew Dinning, commented:
"We are very pleased with the results of the drilling program which has successfully defined continuous high-grade mineralisation in the MC Prospect and importantly has identified a new orientation for mineralisation at the Phantom East Prospect.
These results further reinforce the size potential of the mineralised system and move the oxide mineral resource one step closer to development while the increased understanding and frequency of structurally-controlled high-grade zones is starting to open up future development avenues for the fresh material."
